title: N-(2-Methyl-phen-yl)-1,2-benzoselen-azol-3(2H)-one.
abstract: IN THE TITLE EBSELEN [SYSTEMATIC NAME: (2-phenyl-1,2-benzoisoselenazol-3-(2H)-one)] analogue, C14H11NOSe, the benzisoselenazolyl moiety (r.m.s. deviation = 0.0209 Å) is nearly perpendicular to the N-arenyl ring, making a dihedral angle of 78.15 (11)°. In the crystal, mol-ecules are linked by C-H⋯O and Se⋯O inter-actions into chains along the c-axis direction. The Se⋯O distance [2.733 (3) Å] is longer than that in Ebselen (2.571 (3) Å].
